願公開第3904673号公報参照）。The present invention relates to the construction of monopolar or multipolar plugs, the housing of which comprises a contact element and an insulated electrical conductor connected to the contact element. Plugs of this kind are used, for example, in monitoring equipment for monitoring the lining thickness of motor vehicle brake coatings, and at one end of a single-core or multi-core wire in which the actual wear sensor is arranged at the other end. It is provided. In manufacturing such a monitoring instrument, first the sensor element is attached to one end of the conductor and the conductor is provided with a contact element at the other end. The sensor element is then extruded with a plastic housing, and at the end, which is also provided with a contact element, a plug housing, which is generally made of thermoplastic, is injection-moulded (German Patent Publication No. 2535265). See German Patent Publication No. 3904673).

ている。Moisture protection between an electrical conductor with an insulation made of fluorinated ethylene polymer or a coated wire with a jacket also made of fluorinated ethylene polymer and a thermoplastic housing injection-molded at the plug end In order to make the bond watertight, it is proposed according to the invention to provide an outer coating of thermoplastic on the insulation of the conductor or on the jacket. By taking such measures, it is ensured that the thermoplastic material of the plug housing can form a material bond with the same thermoplastic material of the coating during the injection molding process. Since the problems mentioned here occur especially in conductor insulation or wire jackets made of heat-resistant plastics which are exposed to service temperatures of at least about 120 ° C., plastics based on polybutylene terephthalate or polyamide for the housing of the plug are especially Considered, on the other hand, the insulation or the coating of the jacket can consist of a thermoplastic elastomer based on polyester or a softly modified polypropylene. This kind of plastic is commercially available.
